Abstract:
Non-silicone urea-based adhesives are disclosed which are prepared by the polymerization of reactive oligomers with the general formula X-B-X, where X is an ethylenically unsaturated group and B is a unit free of silicone and containing urea groups. The reactive oligomers can be prepared from polyamines through chain extension reactions using diaryl carbonates followed by capping reactions. Adhesive articles, including optical adhesive articles may be prepared using the disclosed non-silicone urea-based adhesives.
Abstract:
Described herein is a release material comprising: a blend comprising: releasing agent comprising a urethane polymer derived from a polyvinyl polymer containing active hydroxyl groups and an aliphatic isocyanate; and a carrier polymer, wherein more than 50% by weight of the carrier polymer is non-olefinic, and articles thereof.
Abstract:
Non-silicone, urethane-based adhesives are disclosed which are prepared by the polymerization of reactive oligomers with the general formula X-A-B-A-X, where X is an ethylenically unsaturated group B is a unit free of silicone, and A is a urethane linkage. The adhesives are optically clear, self wetting and removable. Adhesive articles, including optical adhesive articles, may be prepared using the disclosed non-silicone urethane-based adhesives.
Abstract:
A method of repairing a light-transmissive substrate is described comprising: providing a polymeric light-transmissive substrate comprising at least one surface defect; filling the surface defect with a polymerizable resin composition having a viscosity ranging from 25 cps to 50,000 at 25°C; applying a pressure sensitive adhesive coated light-transmissive polymeric cover film to at least the filled surface defect; and curing the polymerizable resin composition before or after applying the pressure sensitive adhesive coated film. Also described are repaired polymeric light-transmissive substrates.
